This plugin works well for me on my site. I had to use totally custom CSS, which is no big deal. The pagepeeker integration really helped — I was getting so bored of resizing and uploading thumbnails.

I think one area for improvement would be doing away with external jQuery etc altogether. It’s an option now, but shouldn’t be there at all (I thought this was a no-no in WP plugins.)

Options are well thought-out. I’d recommend the plugin to anyone.
